In that case would a standard part of the interview process become asking the candidate for their home address and calculate how much their commute will cost the company? (Assuming that some companies still have offices and want staff to show up.) Would it be a valid factor in making a hire/no-hire decision? Or picking one candidate over another? What happens if you move during your employment? Would you have to ask for permission since it's going to cost the company money? Or potentially be fired because your commute becomes too expensive?
